In so doing, if, and if so, how product type varies the effects of those two factors was also explored. In order to answer these questions, a 2 (review quality: high vs. low) x 2 (reviewer representation: photos vs. abstract figure) x 2 (product type: experience vs. search) between-subject experiment was conducted online. The product reviews used were mostly positive toward the target product. First, participants who read high quality product reviews evaluated the reviewers, product and seller website more positively than those who read low quality reviews. Second, reviewers profile photos did not evoke higher or lesser social presence than abstract figures did. Likewise, there was no difference in evaluations of reviewers, product, and website between photos and figures. However, photos made people more likely to differentiate high quality reviews from low quality reviews, with high quality reviews eliciting more positive website evaluation than low quality reviews. In addition, photos hindered correct recognition of product descriptions (information given by the seller), although they did not significantly alter the recall of review content (information given by the reviewers). Third, product type interacted with review quality, but not with reviewer representation. For search goods, which refers to the products whose quality is easily predicted before purchase, high quality reviews significantly increased purchase intention. However, the effect of review quality was not found for experience goods, which are defined as the products whose values are hardly assessed before firsthand experience. Theoretical and practical implications of these results were discussed.Introduction 1 Literature Review 4 EFFECTS OF REVIEW QUALITY 4 EFFECTS OF REVIEWER REPRESENTATION 8 PRODUCT TYPE AS A MODERATOR 17 Research Questions and Hypotheses 24 Method 27 PILOT TEST 1 27 PILOT TEST 2 28 MAIN EXPERIMENT 34 Participants 34 Procedure 34 Experiment stimuli 34 Measures 38 Results 41 MANIPULATION CHECK 41 HYPOTHESIS TESTS 41 Affective reactions 41 Behavioral intention 46 Cognitive reactions 48 Discussion 51 THEORETICAL IMPLICATIONS 51 LIMITATIONS AND FUTURE DIRECTIONS 55 Conclusion 59 References 60Maste

[์˜๋ฌธ]This study is to compare the alveolar bone reduction following immediate implantation using microgrooved and smooth collar implants in fresh extracted sockets.Four mongrel dogs were used. Full buccal and lingual mucoperiosteal flaps were elevated and third and fourth premolars of mandible were removed. Implants were installed in the fresh extracted sockets and after 3 months of healing the animals were sacrificed. The mandibles were dissected and each implant sites were removed and processed for histological examination.During the healing, the marginal gaps in both groups that were present between the implant and the walls of the sockets at the implantation disappeared as a result of bone fill and resoprtion of the bone crest. The buccal bone crests were located apical of its lingual counterparts. At the 12 week interval the mean of bone implant contact in the microgrooved group was significantly higher than that of the turned surface group.From the observation in some of microgrooved group, we have found bone attachments to the 12ฮผm microgroove surface and collagen fibers at perpendicular to the long axis of the implants over 8 ฮผm microgrooved surface.Within the limitations of this study, it could be concluded that microgrooved implants may provide more favourable conditions for the attachment of hard and soft tissues and reduce the resorption of marginal bone and the recession of soft tissue.ope
